Maybe weak coil output. Does van engine have LAMDA fuel injection?

Dont know, how do I check? Thought there was a carb on there, limited knowledge on car workings.

Another symptom--doesn't always go back to 900 rpm idle, sometimes stays at 2000, thinking gunk in jet carb or injectors? Will do coil check soon. Thanks

Finally got around to the van with a little good weather--coil spark fine, did find vacuum leak, fixed, solved the sluggishness. Engine still accelerates/decelerated continuously when warm and at idle--any ideas?
